T0 or. whom, it may concern.-

Be it known that I, ALEXANDER C. SCHU- MAN, of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Adding Attachments for Type-Writing Machines; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improved attachment for type-writing machines whereby the total amount of items tabulated on the machine can be ascertained at any time; and it consists in a novel registering mechanism whereby the amounts of any items tabulated or written upon the type-writer can be added simultaneously with the writing thereof at the will of the operator and at any time the operator can determine from the registeringwheels the total amount of any sums or series of sums'which have been registered on the machine.

The device canalso be used as an adding mechanism to calculate totals of items not written on the machine.

The adding mechanism is preferably arranged to be operated by or from the ordinary numeral-keys of the type-writing machine,being thrown into or out of operation at the will of the operator by a very simple contrivance, so that the registering mechanism need not be operated except when desired, which enables the numeral-keys of the type-writing machine to be used for dating and ordinary numeral Work in the usual manner without affecting the registering mechanism, or the numeralkeys may be caused to actuate the registering mechanism simultaneously with their ordinary imprinting actions. In the drawings I have shown theadding attachment applied to the well-known Hammond type-writer; but it is applicable to other makes and kinds of type-writing machines, and I do not restrict myself to the specific application of the invention nor to the specific construction of parts there shown in the drawings.

I will now describe the invention as illustrated in the drawings and refer to the claims appended to the description for summaries of the features and combinations of parts which I deem novel and for which I desire protection.

In said drawings, Figure 1 is a plan view of a Hammond type-writing machine with my improved adding attachment applied thereto.

. Fig. 2 is a detail part-sectioual plan view of the adding attachment and connections. Fig. 3 is a front view of the registering mechanism, partlybroken. Figs. 3, 4, and 5 are details/ Fig. 6 is a detail side view of the adding attachment and portion of the type-writer, partly in section. Fig. 7 is a detail view of the adding-frame escapement mechanism. Figs. 8 and 9 are details thereof. Fig. 10 is a detail sectional elevation of the type-writing machine and adding mechanism, illustrating the devices for spacing the type-writer carriage by the depression of the addingframe. Fig. 11 is a detail plan of Fig. 10. Fig. 12 is an inverted plan View of the plate .I shown in Fig. 2 and connections. Fig. 13 is a detail of one of the carry-over levers. Fig. 14c is a detail view of registering-wheelactuating mechanism shown in Fig. 2, showing the segment in mesh.

112 designates the anvil of a Hammond typewriter, on which is mounted the type-shuttle 114, which is vibrated by means of a vibrating shuttle-arm 58, which is actuated by either of two driver-arms 80, each of which is operated by suitable connections from curved bars A, each of which extends over one-half of the series of key-levers A, that are suitably fulcrumed at A and when the outer end of a key-lever is depressed its inner end is raised, lifting bar A, thereby rocking the connected pusher-arm 112 which moves the shuttle-arm and shuttle more or less, according to the key depressed. Upon the release of the key the parts are returned to normal position by suitable springs. An impression is taken from the type on the shuttle 11st at the proper time and point by means'of the hammer 13, which is actuated by suitable mechanism controlled by the lift-bar A ,which is operated by the key-levers, like bars A. As all the foregoing parts are constructed and operated just as in the ordinary Hammond type-writing machine in common mercantile use, it is not necessary to more particularly describe them.

The adding ct/tachinent.A series of similar registeringwheels B are loosely mounted on a shaft b, journaled in a frame Z. These wheels have numbered flanges l3, and fixed on shaft 1) beside each wheel B is a star-wheel l), which is engaged by a double-beveled spring-pressed pawl attached to the adjacent registering-wheel. These star-wheels and pawls permit the registering-wheel to be independently rotated on shaft 5 and at the same time permit them in setting he adding mechanism to be rotated with the shaft back to zero position and then stopped. The shaft 12 can only be rotated in one direction, (to reset the registering-wheels,) being provided with a notched disk b engaged by a spring-actuated pawl b on the frame, which prevents forward rotation of shaft 7). Each registering-wheel (except that of highest denomination) is provided with a carry-over pin 13, which is adapted to contact with a lug c on the short arm 0 of an oscillating lever, the longer arm 0 of which extends beside the wheel of the next higher denomination, and on the extremity of arm 0 is pivoted a dog 0 which is adapted to engage with and turn the said higher wheel when the carry-over lever is moved inwardly, as hereinafter described. The dog 0 is normally pressed inward bya spring 0 but is arrested in proper position by a lug c on arm 0, as shown. The carry-over levers are all loosely pivoted on a shaft 0 and are kept from free vibration by suitable friction devices, frictional springs 0 being shown for this purpose, said springs being fast to a rod C fixed in the frame. On the long arm 0 is a cam projection c, which is adapted to be engaged by an arm d on a rotatable shaft D, and the arms (Z for actuating the carry-over levers of disks of successively higherdenominations are so placed on the shaft that they will actuate these levers in succession instead of simultaneously, so as to enable the disks to carry over successively at one rotation of shaft D, if neces sary to do so, as would be the case in adding three hundred and thirty-three to six hundred and sixty-seven.

Adjacent to dogs 0 is a roc (shaft E, having a series of fingers c, which are adapted to engage pins 0 on dogs a and move the latter out of position to engage the registeringwheels when the latter are to be reset. The shaft E may be rocked by means of an oscillating lever E, fulcrumed on the frame and having a beveled end engaging a pin E on shaft E. The otherend of the levercomes beneath a button b splined on the end of shaft Z) and normally pressed outward by a spring (i but upon pushing the button inward lever E is oscillated, rocking shaft E and causing fingers e to move dogs c out of position to engage the registeririg-wheels, and then by rotating button I) the shaft Z1 can be turned so as to rotate registering-wheels l5 backward until the pins 13 strike the rear side of lugs c, which arrests the registering wheels at zero position. I would state here that on the forward or registering movements of wheels 15 the movement (one-tenth of a revolution) imparted to such wheels for each unit registered thereby is sufficient to cause pin 13 to engage lug 0, shift lever C, and move past the lug, so that the pins B will not interfere with the carryingover movements of lovers 0. Each time any number has been registered by the wheels shaft D is rotated once, so as to cause the carrying-over operations, if such be necessary.

In the machine shown the frame Z, with the registering-wheels and devices above described, is vertically movable, being guided on upright rods Z, attached to the main frame, and the frame is normally pressed upward to highest position by a coiled spring Z surrounding a rod Z", as shown. After each item is registered the frame is depressed before beginning the registration of a new item, and this depression causes the rotation of shaft I), which is provided with coarse angular spiral grooves (Z in its lower end which are engaged by dogs (1, pivoted on a support d, attached to the main frame, and during the downward movement of the frame the dogs (Z riding in the grooves (1 cause shaft D to rotate once, thereby effecting the carryover operations, as above described. On the upward movement of the frame the dogs sim ply ride or back out of the grooves without rotating the shaft D. The shaft D is suitably journaled in frame Z so it can reciprocate therewith and rotate therein; but its lower end passes freely through the opening in support (Z In the present invention the several registcring-wheels are successively operated by a single segment, which is actuated from the key-levers, as hereinafter described, and at each depression of a number-key (when the registering n'iechanism is in operation) the frame Z is shifted so as to bring a disk T of lower denomination into position for acture tion by means of the spring Z the shifting of the frame 75, however, being controlled by an escapeinent mechanism, which I will now describe.

[he csc pement median ism/or the registering devices.Attached to the rear side of frame Z is a fixed vertical ratchet F, whose teeth correspond in number and distance apart to the registering-wheels l3. Beside ratchet F is a corresponding movable rack F, which is guided by slots and pins and upheld by a spring I, as shown. These racks are alternately engaged by a dog f, pivoted on a laterally-oscillatingplatef, which is supported on a vertical rod f pivoted in suit able bearings on the main frame of the type writer. The oscillation of plate 1" is limited by a slotted stop-barf, attached to the frame, as shown. As plate 1" oscillates dog f is engaged alternately with racks I I and the frame Z permitted to rise by a step-by-step movement, similar to the carriageescapemen t action of a type-writing machine.

The

plate f is oscillated by a rocking lever G, the front end G of which is bent laterally outward and provided with a notch adapted to engage the edge of plate f, so as to vibrate the latter and at same time permit lever G a greater movement than is necessary to actuate the plate, the lever G performing addition a1 functions, hereinafter explained. The lever G extends rearwardly beneath the paper-carriage and in rear thereof is fulcrumed on a pin G attached to the main frame, and to the rear end of lever G is attached an an gular arm G which extends to the hammer 13 and is engaged by a notched plate G attached to the side of the hammer, so that the latter imparts oscillating movements to lever G. A releasing-lever F is pivoted to the frame Z and provided with a thumb-piece or key on its upper end, while its lower or inner side i depends beside the dog j and is adapted to engage a pin f on the dog when the key on lever F is depressed, so as to disengage the dog from the racks F F and allow the frame Z to rise. The normal position of said frame is in its elevated position, and it is not intended to be depressed until it is desired to add an item, Then the frame is depressed and is released by the escapement mechanism above described each time a numeral is printed.

The devices for shifting the registeringwheels in recording items. The shaft Z), carrying registering-wheels B, is vertical in the construction shown and is located at the left hand side of the machine at a point adjacent to the type-shuttle. The registering-wheels are accessible at this point and are adapted to be engaged by a vibrating segment H, which is arranged. horizontally and is sup ported at one end on an oscillating lever l (to which the segment is pivoted) and is further supported by a pin J on a vibrating plate J, loosely attached to a shaft J pivoted between suitable bearings on the main frame, as shown. The pin J engages longitudinal slot H in segment H, so that the latter can reciprocate on the pin. The plate J is upheld by a plate j, fixed to shaft J (see Figs. 2 and 12,) so that it can oscillate on the shaft J An angular leverj is pivoted to the under side of plate J and has a tooth 7' on one arm adapted to engage 'a notch j in platej, so as to lock the plates J j together normally, a spring j being arranged to normally hold the tooth j in engagement with notch The other arm of lever j projects in rear of the plate J and is adapted to be struck by finger g on the lever G when the latter is moved by the type-hammer, as above explained. The shaft J is provided with a cam J on its lower end, which lies above and is engaged by the lift-bar A, so that as the latter is lifted by the keys shaft J is turned so as to swing plates J j toward the registering-whoels, and thus through pin J move segment into mesh with a registering-wheel, if the latter are in position for mesh therewith... 'Wl

the key is released, bar J and plates J j are rocked backward by a spring J. A spring J is also connected to plate J and to a suitable adjacent fixed point on the frame, and if catch j disengages notch 7' spring J will immediately throw plate J backward, so as to withdraw the segment H from mesh with a registering-wheel before shaft J is thrown backward, which is necessary; otherwise the segment would remain in mesh on both strokes, and therefore would return the registeringwheel to starting position and fail to register accurately. The segment H is thrown forward in position to mesh with a registering wheel each time the left-hand bar A is raised by the depression of a key; but the segment H is not oscillated or reciprocated unless one of the numeral-keys is depressed, and then it moves more or less, according to the numeral of the key. In practice the segment H will be vibrated by the depression of the ordinary numeral-keys of the type-writing machine; but I prefer to arrange all the numeral-keys at one side of the machine, so that all such keys will actuate the left-hand type-controlling lift-bar A, (two such bars, one on righthand and one on left-hand side of machine, being employed in the Hammond type-writ ing machines.) The keys bearing the numbers 1 to 9, inclusive, on the drawings are thus arranged. Except for this changing of the location of the numerals on the keys (and consequent rearrangement of characters on the type-shuttle) no other change is necessary in the mechanism of the Hammond type-writing machine when the invention is applied thereto.

The lever l, carrying the segment H, is almost a counterpart of the shuttle-arm 53, which is used in the Hammond machine to actuate the type-carrier. Itis, however, only operated by the left-hand driver-arm, and consequently needs but one slot i to engage therewith. (See Fig. The leverl is pivoted on the sleeve of arm 53 and projects forwardly beyond the ordinary stop-rod ring A of the Hammond type-writing machine to permit the segment H to be pivoted thereto and work clear of the stop-rods A of the machine. The lever 1 works below the ordinary shuttlearm 53 of the machine and is not vibrated until the proper key is depressed. Then the left driver-arm engages the notch c'and moves the lever I and segment H until the arm I on the lever 1 brings up against the stop-rod 'A, which has been raised by the de pressed key, (as usual in the Hammond typewriting machine.) The arm I of lever lis provided with an upstanding lug 1 which is engaged by the shuttle-arm 53 of the machine when a nu moral-key is depressed, so that the proper movement of segment H is insured. It may notbe necessary to use both the slot 6 and the lug P, but I show both in the drawings. The arm I may be perforated, as at to permit the passa e of underlying stopn'ods when the lover I is in normal retracted posi" tion. The lever I is returned, with segment H, by the action of shuttle-arm 53, just as the shuttle of the Hammond machine is returned, and is arrested in normal position by a stop 1 attached to the side of the upper stop-rod ring, as shown.

The iabulctting device.Pivotally suspended from the under side of the frame Z is a link K, having angular notches K in one edge which are adapted to engage a roller fixed on the short arm of a bell-crank lever 7t, which is pivoted at 76 on a suitable support on the main frame, as shown. The longer arm of lever 70 is carried down under the hammer-release and spacing bar A of the type-writing machine, which is raised every time a key is depressed, or each time the spacing-bar is depressed, as in the ordinary Hammond type-writing machine. When the frame Z is depressed, the roller is, riding over the notches K, oscillates lever 7t and causes it to lift bar A" each time itrides over a notch, sufficiently to operate the carriageescapement and allow the carriage to move down (just as if the ordinary space-bar was operated) one space for each notch K in link K. The link is normally held in engagement with roller 70 by means of a roller L on one end of an oscillating lever L, which is pivoted at L on a fixed support secured to the frame, and is kept normally in position to hold the link in engagement with the tooth by means of a double-acting spring L attached to the fixed pivot L and engaging between lugs L on the lever, so as to return the lever L to central position whether it be rocked to right or left. The rear end of lever L projects close to the guide-bar M of the paper-carriage M of the type-writing machine, and on this bar is fixed a pin m, which is adapted to strike a dog Z, pivoted to the inner end of lever L,and move the lever so as to disengage roller L from link K, (as the carriage moves to the left,) so that the link rocks or vibrates over the roller 7t" instead of rocking the lever. A spring K is arranged to press the link inward toward the roller 7;, so as to permit the roller L to move behind the lever as soon as permitted by the carriage; but this spring is not sufficiently powerful to cause the link to actuate the lever when roller L is displaced.

This device is quite useful in tabulating work, for it enables the operator to rapidly space the carriage without manipulating the space-key. For example, after entering an item of merchandise the operator can depress frame Z, and this movement of the frame-depressing link K vibrates lever 7t and operates the carriage release or escapement mechanism, permitting the carriage to move down until the lever L is displaced by pin on (which is always at a certain point) or until the frame Z is fully depressed. If when fully depressed the carriage must move still farther to the tabulating-point, the carriage can be moved on by manipulating the spacekey of the machine in the ordinary manner. When the frame Z is fully depressed, it is in position to begin registering with the wheel of highest denomination. If, however, some smaller denomination is to be registered, the frame Z must be raised until the desired registering-wheel is in position for engagement with segment H. This may be accomplished by means of the release-key F, but I preferably attach a key-lever 7a to lever 70, lever extending to a convenient position so that by depressing this lever 73 the bar A will be raised sufficiently to fully release the hammer 13, which, making its full stroke, causes lever G to operate the escapement F F of the frame Z and permit it to rise one notch, and this allows the paper-carriage to simultaneously move one notch to the left. Thus if the tabulating-point was at 50 on the index,and owing to the small denomination of the item the carriage must move on to 53 and the registering-frame rise three notches, three depressions of lever 70 will effect both the proper shifting of the carriage and the proper raising of the registeringframe.

The frame Z may be provided with an index N, moving past a fixed indicator N, by which the operator can tell at a glance the de nomination of the registering-wheel which is in position for actuation by the segment I-I.

Operation: The particular operation of the several parts have been explained above in connect-ion therewith. The general operation is as follows: While the frame Z is in its uppermost position the type-writer can be operated as usual, so that the dates and character of items can be recorded, written without the registering -wheels being affected. After writing out the item the operator depresses frame Z, this through the described mechanism simultaneously spaces the typewriter carriage to the left,until the tabulatingpoint is reached or (if it stops short of that point when frame Z'is fully depressed) it can be moved down by the ordinary spacing-key. This tabulating-point would correspond to the highest denomination of disk, (tens of thousands in the machine shown,) and if the amount of the item recorded was in this denomination the operator would simply write it on the machine. The amount would be registered on the adding mechanism simultaneously with the writing thereof on the paper. At the end of the item the frame Z has risen so that the date and character of the next item can be written without affecting the adding mech anism, if the amount of the next item is, say, one hundred dollars. After the frame Z has been fully depressed the release-key 70 is operated until the frame Z rises to the hun dreds point on the scale. Then the amount of item is written. The frame Z should be raised fully and depressed fully between each registering operation, so as to insure the proper complete rotation of the carry-over devices.
